1. When will the rainy season end in Tohoku? (Situation in 2026)

Many people searching for information about the end of the rainy season in Tohoku in 2026 are looking to know "when the rainy season will end this year" and "whether it will be earlier or later than average."

According to the Japan Meteorological Agency's preliminary forecast for the start of the rainy season in 2026, the rainy season is expected to begin around June 20th in southern Tohoku and around June 21st in northern Tohoku. This is 8 days later than average for southern Tohoku and 6 days later than average for northern Tohoku.

On the other hand, the end of the rainy season is announced based on the weather progression and future forecasts, so the timing varies from year to year.

Therefore, when checking the forecast for the end of the rainy season in Tohoku, it is important to check the latest weather information.

2. What is the average time of year for the end of the rainy season in Tohoku?

According to past data from the Japan Meteorological Agency, the average end of the rainy season in southern Tohoku is around July 24th, and in northern Tohoku it is around July 28th.

In other words, the end of the rainy season in the Tohoku region is typically around late July.

However, the end of the rainy season cannot be definitively marked by a specific day; it is a seasonal phenomenon that marks the transition from spring to summer. The Japan Meteorological Agency also explains that, on average, there is a transition period of about five days between the start and end of the rainy season.

3. Reasons why skin tends to become rough after the rainy season ends

1) UV rays tend to be stronger

After the rainy season ends, sunny days increase, and it's a time when you tend to spend more time in the sun.

Excessive exposure to ultraviolet (UV) rays can lead not only to sunburn but also to skin problems such as age spots, dullness, and wrinkles. The Ministry of the Environment's UV radiation environmental health manual also lists wrinkles, age spots, and solar lentigines as effects of UV rays on the skin, in addition to sunburn.

In particular, those who were lax about UV protection during the rainy season should be careful of the sudden sunshine after the rainy season ends.

 

2) Pores tend to get clogged with sweat and sebum.

After the rainy season ends, temperatures rise, and the secretion of sweat and sebum tends to increase.

If sweat and sebum remain on the skin, it can lead to stickiness, clogged pores, and acne.

Areas of the skin that tend to get sweaty, especially those covered by masks, bangs, or hats, are prone to accumulating sebum and sweat, so extra care should be taken.

 

3) Inner drying due to air conditioning

In the summer, even if you sweat outside, your skin tends to dry out indoors due to air conditioning.

If your skin feels oily on the surface but tight underneath, you may have an inner dryness condition.

Continuing to use skincare products that remove too much sebum in this condition can lead to dry skin and a disruption of the skin's barrier function.

 

4) Skin is easily affected by differences in humidity and temperature.

The transition from the rainy season to summer is a time when humidity and temperature tend to fluctuate significantly.

Therefore, you may experience redness, itching, dryness, and acne that you wouldn't normally notice.

After the rainy season ends, it's important to focus not only on refreshing skincare but also on moisturizing care to protect your skin.

4. The correct skincare methods after the rainy season ends

1) Use sunscreen every day.

After the rainy season ends, it's important to make it a habit to use sunscreen even if you're only spending a short time outdoors.

Besides the face, the neck, ears, backs of the hands, and arms are also areas that are easily exposed to ultraviolet rays.

During seasons when you tend to sweat a lot, it's a good idea to reapply sunscreen not just once in the morning, but every 2-3 hours.

2) Gently wipe away sweat without rubbing.

Leaving sweat on your skin can lead to stickiness and irritation.

However, rubbing too hard with a towel can easily cause redness and skin irritation due to friction.

When wiping away sweat, gently pat it with a clean towel.

 

3) Be careful not to "over-cleanse" your face when washing it.

After the rainy season ends, excess sebum can become a concern, but repeatedly washing your face with a strong cleanser can strip away essential moisture from your skin.

It's important to wash your face gently with lather, without rubbing your skin, as a basic rule in the morning and evening.

Those who are concerned about oily skin should not forget to moisturize after washing their face.

 

4) Don't skip moisturizing, even in summer.

It's easy to think that you don't need to moisturize in the summer because your skin gets sticky, but after the rainy season ends, your skin is prone to dryness due to the effects of UV rays and air conditioning.

Use a lightweight lotion, gel, or cream to balance the moisture and oil levels in your skin.

If you're concerned about stickiness, it's also a good idea to choose a moisturizing product with a lighter, more refreshing texture.

5. Treatments you can consult about at a cosmetic dermatology clinic.

If you are concerned about pores, acne, dullness, blemishes, or dryness after the rainy season ends, you can consult with a cosmetic dermatologist to have your skin condition checked and receive advice on skincare.

 

1) If you are concerned about pores and sebum

Those who are concerned about clogged pores due to sweat and sebum may consider pore cleansing or peeling treatments.

However, skin is more susceptible to irritation when it is red or has just been exposed to sunlight, so it is necessary to make judgments based on your skin condition.

 

2) If you are concerned about dullness or uneven skin tone

If you are concerned about dullness or uneven skin tone after the rainy season ends, we may discuss toning treatments or brightening care tailored to your skin condition.

Since skin is more sensitive immediately after exposure to ultraviolet rays, it is recommended to consult a cosmetic dermatologist about the best timing for treatment.

 

3) If you are concerned about dryness or inner dryness

If your skin feels oily on the surface but tight underneath, it's important to re-evaluate your moisturizing routine.

If you continue to experience dryness or skin instability that is difficult to improve with self-care, consult a professional about skincare and moisturizing treatments tailored to your skin condition.
